GlowShift’s Black 7 Series Wideband Air/Fuel Ratio Gauge is essential when tuning any performance vehicle. Installing this gauge allows you to closely monitor and tune your vehicle's air to fuel ratio giving you multiple benefits that include reduced emissions, higher fuel economy, and maximized power and engine performance by allowing you to carefully map out your vehicle's air to fuel ratios throughout the range of RPM and manifold pressure which results in maximized power output.

GlowShift’s Wideband Air to Fuel Ratio Gauge features an easy to read blue digital numeric readout that will display your vehicle’s air/fuel ratio from 10.0 to 20.0 AFR down to one decimal place, as well as having a three color LED ring that quickly indicates rich, lean, and optimal values. These incredibly accurate readings are attained by utilizing the included Bosch LSU 4.9 Wideband Oxygen Sensor. The 4.9 wideband oxygen sensor is installed to your vehicle's exhaust with the included weld in bung, and the included 13' sensor wire easily connects to the back of the gauge with modular connectors.

This wideband air/fuel gauge also comes standard with a 0 to 5 volt digital output that allows you to connect it to virtually any data logging or engine management system. This gauge is intended to match GlowShift’s Black 7 Color Gauge Series; however they do not change colors due to the dual read out and digital display of the gauge. Free lifetime technical support, one year limited warranty, and full installation instructions come with every Black 7 Series Digital Wideband Air/Fuel Ratio Gauge.

Rich: 10 ~ 12.9 AFR | Optimal: 13 ~ 17.9 AFR | Lean: 18 ~ 20 AFR

Note: The included Bosch 4.9 LSU Wideband Oxygen Sensor includes Bosch’s 30 day manufacturer’s warranty. GlowShift does not warranty this sensor after that 30 day time frame.
